Application filed March 3, 1914. Serial No. 822,127.

In the preferred form of my invention, a I

heated revoluble roller provided with corrugations coacts with a secondheated revoluble roller provided with corrugations which intermesh withand are movable longitudinally with reference to the corrugations of thef first roller, the latter being provided with a cam which operates anoscillatory lever mechanism whereby the second roller is movablelongitudinally in contact with said first roller.

In the accompanying drawings, Figure 1 is a front elevation of a machineembodying my improvements; Fig. 2 is an elevation of the end thereoffrom which it is operated; Fig. 3 is an elevation of the opposite end ofthe machine; Fig. 4 is a perspective view of the detached levermechanism; Fig. 5 is a broken perspective view .of the heating-mechanism; Fig. 6 is a sectional view'of an end of a corrugating rollerand its journal; Fig. 7 is an enlarged plan view of a section of acorrugated roller; Fig. 8 is an enlarged sectional view of apart of acorrugated roller; and Fig. 9 is a broken sectional view of a modifiedroll construction.

The machine, as illustrated in the drawings, comprises the housings 1provided with the blocks 2 in which are mounted the journals 3 and 4 ofthe corrugated roller 5, and the blocks 6 in-whioh aremounted thejournals 7 and 8 of the corrugated roller 9.

The journal 3, which carries the fast and loose pulleys 10 and 11, hasfixed thereon a cam12. A lever 13, fulerumed on the hearing 14 fixed tothe housing 1, is provided with the bifurcations 13 forming a yokewithin which revolves the cam 12, the yoke being provided with a roller14' which engages the cam whereby the lever is oscillated when theroller 5 is revolved. A channel 7' in the journal 7 has a loose collar15 engaged therein, the collarbeing provided with the laterallyextending hubs 15, on which are engaged the links 17 connected with the,

bifurcations 13, whereby theosoillation of the lever 13 effects thereciprocation of the roller 9.

The rollers are made hollow for the purpose of facilitating theoperation of heating them, and, as illustrated in Figs. 7 and 8, theycontain the radial passages 18 for heated gases. The heating operationis suitably effected by the introduction, through the journals of therespective rollers or either of them, of an air pipe 19 having aperforated section 20 within the roller and a gas pipe 21 having aperforated section 22 within the roller, the jets delivered from therespective perforations intermingling to provide the desired combustiblemixture' A blower 23 may be used to force'air through the pipe 19. Itwill be understood that instead of heating by gas, the operation may beeffected by forcing steam through the pipe 19.

As shown in Fig. 9, the lower roller 5 may have its ribs 5 provided withnotches 5 for holding the paper against lateral movement with the roller9, the paper being engaged in the notches or by the irregularities ofsuch ribs to provide the necessary frictional resistance againstslipping.

In operation, the revolution of the corrugated roller 5 effects thesimultaneous revolution of the corrugated roller 9 intermeshingtherewith, while the revolution of the cam 12 with the roller 5 effectsthe oscillation of the lever 13, which acts through the links 17 andcollar 15 to effect the reciprocation of the roller 9, whereby the paperboard passing between the rollers 5 and 9 is corrugated by therevolution of the rollers and ironed by the longitudinal movement of thereciprocating roller. The effect of this operation is to give thedesired set to the corrugated product by ironing it simultaneously withcrimping it, with distinct improvements in the matters of economy ofoperation, smoothness of finish and perfecing the revolution of theother of said rollfl ers, and means whereby the revolution of one ofsaid rollers effects the longitudinal movement of the other of saidrollers.

4. The combination of housing mechanism, a corrugated roller journaledtherein, a second corrugated roller journaled in said housing mechanismand movable longitudinally therein, means whereby said first rollerreciprocates said second roller, one or more of 'said rollers beinghollow and having passages for a heating medium, and means for heatingone or more of said rollers.

5. The combination of a corrugating roller having means for obstructingthe lateral movement of material pressed thereon with a corrugatedroller coacting with said roller first named, and means forreciprocating said .second roller longitudinally.-

6.,The combination with a pair of intermeshing corrugated rollers, withmechanism whereby said rollers are revolved, and mech RALPH w. NAZEL.
